  • - for the compensation of transmission lossiness of multi-switches and of connecting cables in a 5-cable distribution network;
  • - can be cascaded with the 5-cable system components: shifters, demultipliers and multi-switches;
  • - level adjust of the signal at each input;
  • - adjustable integrated equalizer and two-step amplifier in terrestrial TV channel;
  • - fixed pre correction of amplitude-frequency characteristics by 7 dB (5 dB for SA502) for intermediate frequency of CTB; SA501, SA502
    4-channel head amplifier of CTB and  terrestrial TV channel with integrated switching power supply enabling to provide power: upwards 18 V DC along the lines of H polarization and14 V DC along the lines of V polarization; downwards 18 V DC (commuted), along the lines of H polarization and14 V DC along the lines of V polarization; 12 V DC via Terr. TV input

4-channel linear amplifier of CTB and  terrestrial TV channel; powered by an external source via H polarization lines; pass-through of power supply along V and H polarization lines (commuted via H lines); supply voltage 12 V  at the Terr. TV input (commuted)
